Lower vessel head of container and container comprising lower vessel head

Abstract

The invention discloses a lower vessel head of a container and a container comprising the lower vessel head. The upper end of the lower vessel head comprises a top opening used for being connected with the bottom of the container. The lower end of the lower vessel head comprises a material discharge opening which is smaller than the top opening, wherein the center of the material discharge opening deviates from the center of the top opening in a horizontal direction. The material discharge opening of the lower vessel head is closer to the outside of the container, so that an operator no longer needs to stand under the bottom of the container when the material discharge opening is opened\closed, thereby facilitating the operator to close / open the material discharge opening. Due to the fact that a common material discharge opening is outwards communicated with a material discharge pipeline, and the material discharge opening is closer to the outboard of the container, the material discharge pipeline can be shortened, thereby effectively preventing sticky liquid materials from accumulating inside the pipeline.

Description

technical field [0001] The invention relates to the technical field of storage and transportation containers, in particular to a lower head of a container and a container including the lower head. Background technique [0002] Storage and transportation containers, such as intermediate bulk containers, can be used to store and transport liquid materials. When discharging, the liquid material in the container can be discharged through the discharge port under the container by its own gravity. Taking an intermediate bulk container as an example, in order to facilitate transportation, turnover and storage, it usually consists of two parts: a container and a supporting frame. Liquid materials are stored in containers supported by support frames. The container includes an upper head, a cylinder body and a lower head connected from top to bottom. The bottom of the lower head is provided with a discharge port, and a discharge pipeline is connected to the outside, and a discharge ...

AI Technical Summary

Problems solved by technology

If the diameter of the container is large, the operator needs to drill to the bottom of the container when operating the discharge valve, which brings inconvenience to the operation

In addition, because the general discharge port will connect the discharge pipeline to the outside to discharge the material, the discharge port is set at the bottom center of the head, which also makes the discharge pipeline longer. It is understandable, especially if the container is placed flat on the ground, The longer the connecting pipe, the slower the flow rate of the liquid material will be, and the more material will remain in the pipe, which may even cause pipeline blockage

[0004] In addition, because the arc of the elliptical, butterfly and spherical heads is very small, and the bottom of the conical head with folded edges is a plane, when the viscosity of the liquid material in the container is high, the discharge speed will appear. It is extremely slow, and the phenomenon that the material is not easy to be discharged requires manual assistance, and the cleaning of the material is also very complicated.

This not only affects work efficiency, but also causes waste of materials and increases the workload of operators

[0005] Therefore, it is necessary to provide a lower head of the container and a container including the lower head to solve the above-mentioned problems of inconvenient operation and slow discharge.
